Answer:
y = x + -2.3
x = -y - 2.3 (but why would one need this?...)
Step-by-step explanation:
(6.1 - (-9.7))/(8.4 - (-7.4)) = 15.8/15.8 = 1
6.1 = 8.4 + b
b = -2.3
Answer:

Answer:
Hip breadths less than or equal to 16.1 in. includes 90% of the males.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 14.5
Standard Deviation, σ = 1.2
We are given that the distribution of hip breadths is a bell shaped distribution that is a normal distribution.
Formula:

We have to find the value of x such that the probability is 0.10.
P(X > x)
Calculation the value from standard normal z table, we have,

Hence, hip breadth of 16.1 in. separates the smallest 90% from the largest 10%.
That is hip breaths greater than 16.1 in. lies in the larger 10%.
The total number of cups of sugar needed will be given by:
Total amount=(number of bottles)×(number of cups of sugar per box)
number of bottles to be made is 5 bottles
number of cups per box is 3/4
thus the total number of cups required will be:
Total amount=3/4×5=3 3/4 cups
